Phys. Rev. B 43, 62–70 (1991)Radiative electron capture by channeled ionsReceived 30 May 1990; published in the issue dated 1 January 1991 Much experimental data have been accumulated relative to the emission of photons accompanying electron capture by swift, highly stripped channeled ions. Recent data suggest that the photon energies may be less than that expected from simple considerations of transitions from the valence band of the solid to hydrogenic states on the moving ion. We have studied theoretically the impact-parameter dependence of the radiative-electron-capture process, including the effect of the ion’s wake and capture from inner shells of the solid on the photon-emission probability, and using a statistical local-density approach. Numerical comparisons of our results with experiment are made. © 1991 The American Physical Society URL:
